View routing in chip planner

Is there any way to view the routing in the chip planner? I would like to see which way a signal has been routed and how much routing resources are available at different locations.

The "Routing Details" checkbox under layer settings is unavailable. Is it simply not possible in Quartus Lite? Or maybe it's not available for Cyclone V?

I have tried the "Generate Fan-Outs" and then "Expand connections" and this will give me some idea of where a single signal is going but it's impossible to view multiple signals or get any idea of which routing resources are occupied.

I'm using:

Quartus Prime Lite 15.1.0

Cyclone V SE

    I don't like Routing Details and never use it, so not sure why it's not working, but have used Expand Connections many times in Cyclone V. I would be surprised if this were disabled for Lite but not sure. I always do a report_timing in TimeQuest on the path i'm interested in, right-click on the result and Locate -> Chip Planner. Then I double-click on the path in the Selection History(you may not have to do this for a single path, but you do if you locate multiple paths) and then click Expand Connections. I thought it worked after doing a Generate Fan-Outs but it's been many years since I've tried and before Cyclone V.
